Answers

Answer 1

Answer:

A) 1/(3x+1)

Step-by-step explanation:

(x+2)/(x³+2x²-9x-18)÷(3x+1)/(x²-9)

(x+2)/(x+2)(x+3)(x-3)÷(3x+1)/(x+3)(x-3)

since it’s dividing by a fraction, invert and multiply

(x+2)/(x+2)(x+3)(x-3) times (x+3)(x-3)/(3x+1)

The (x+2)’s cancel out.

The (x+3)’s cancel out.

The (x-3)’s cancel out.

You are left with 1/(3x+1)

1/10 of the counters in a bag are blue. 1/2 of the counters are red. 2/5 of the counters are yellow. Which of the ratios below shows the ratio of blue to red to yellow?

Answers

Answer:

well 1/10 are blue, 5/10 are red, and 4/10 are yellow.

1/10 blue

5/10 red

4/10 yellow

I don't really know how to answer this question but I hope me converting the ratios helps :)

Step-by-step explanation:

Given: 1/10 blue
1/2 red
2/5 yellow


First, make it so that each if their whole (denominator, or the right side) is equal.

We already know that 2 and 5 are common factors of 10, so we get them to the number 10 by equal multiplication.


1/10 - blue
1/2(5) = 5/10 - red
2/5(2) = 4/10 - yellow

Now just take their numbers in order.

In trapezoid MNPQ shown below, MN || QP, m&M = 108°, m&P = 4x - 5, and
mxQ = 3x + 21. What is the number of degrees in m«N.

Answers

Answer:

Answer:

The answer is below

Step-by-step explanation:

A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).

In trapezoid MNPQ:

∠M + ∠Q = 180° (angles on the same leg are supplementary)

108 + (3x + 21) = 180

3x + 129 = 180

3x = 51

x = 17

Also:

∠N + ∠P = 180° (angles on the same leg are supplementary)

∠N + (4x - 15) = 180

∠N = 180 - (4x - 15)

∠N = 180 - 4x + 15

∠N = 195 - 4x

substitute x = 17°:

∠N = 195 - 4(17)

∠N = 127°

Answer:

The graph under the "U" graph

Step-by-step explanation:

If the exponential model f(x)=14(5)x is written with the base e, it will take the form A0ekx. What is A0 and what is k?

Answers

Answer:

We have:

f(x) = 14*(5)^x

And we want to write this in the form:

g(x) = A*e^(k*x)

We want to have f(x) = g(x)

This is ratter easy.

The general case is:

A*(r)^x = B*e^(k*x)

Here we have:

A = B

Then:

(r)^x = e^(k*x)

Now we can remember the relation:

(a^x)^y = a^(x*y)

Then we can write:

e^(k*x) = (e^k)^x

Then we have:

(r)^x = (e^k)^x

Then we must have:

r = e^k

Now let's go to our case:

14*(5)^x = A*e^(k*x) = A*(e^k)^x

Then we have:

14 = A

5 = (e^k)

With this equation we can find the value of k.

ln(5) = ln(e^k) = k

ln(5) = k

Then the equation g(x) is:

g(x) = 14*e^(ln(5)*x)

Answer:

A0=14 k +ln9

Step-by-step explanation:

To rewrite the model with the base e, we use the fact that for all b>0,

b=eln(b)

Using this property, and then the power property of logarithms, on 9x, we find that

(9)x=eln(9x)=exln(9)=e(ln(9))x

So we find that

14(9)x=14eln(9)x

So A0=14 and k=ln(9).

In how many ways can a quality-control engineer select a sample of3 transistors for testing frm a batch of 100 transistors?

Answers

Answer:

161700 ways.

Step-by-step explanation:

The order in which the transistors are chosen is not important. This means that we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

3 transistors from a set of 100. So

[tex]C_{100,3} = \frac{100!}{3!(100-3)!} = 161700[/tex]

So 161700 ways.
